Abstract

L'invention concerne le pré-traitement de données audio pour générer des paramètres associés à la mise à l'échelle temporelle, lequel pré-traitement permet de diminuer la puissance de traitement nécessaire à la mise à l'échelle temporelle en temps réel de données audio. Une structure de données audio augmentée comprend les données audio et les paramètres. Les paramètres pour une trame des données audio permettent d'identifier les blocs de meilleure correspondance pour la mise à l'échelle temporelle ou de représenter un tracé d'échelle de décalage par opposition au temps, qui peut être interpolée pour déterminer un décalage. La mise à l'échelle temporelle en temps réel met en oeuvre les blocs que les paramètres permettent d'identifier au lieu d'effectuer une recherche pour les blocs de meilleure correspondance. Les paramètres peuvent également indiquer laquelle des trames représente un silence et peut être mise à l'échelle différemment de trames qui ne représentent pas un silence.
